Description

フレキシブルプリント基板の製造方法、基板製造用治具および基板製造装置Flexible printed board manufacturing method, board manufacturing jig, and board manufacturing apparatus
　本発明は、フレキシブルプリント基板の製造方法、基板製造用治具および基板製造装置に関する。 The present invention relates to a flexible printed circuit board manufacturing method, a board manufacturing jig, and a board manufacturing apparatus.
　近年、多彩な動きをするロボットが登場する等、ロボットの発展が著しくなっている。また、人体や衣服に装着可能なウエアラブル電子機器も、様々な機器で開発、実用化が進んできている。これらのロボットやウエアラブル電子機器には、電力供給用や電気信号伝送用の電線が多数使用されているが、一般的に電線は銅線を芯とし、その外周を絶縁体で被覆した構造になっているため、電線自体に伸縮性はほとんどない。このため、たとえばロボット等においては、その関節の動き等を妨げないように、電線長に余裕を持たせる必要があり、このことが小型、軽量化等に向けた設計上、実用上の支障となる。 In recent years, the development of robots has become remarkable, such as the appearance of robots with various movements. In addition, wearable electronic devices that can be worn on the human body and clothes have been developed and put into practical use with various devices. These robots and wearable electronic devices use a large number of electric wires for power supply and electric signal transmission. Generally, the electric wires have a structure in which a copper wire is the core and the outer periphery is covered with an insulator. Therefore, there is almost no elasticity in the electric wire itself. For this reason, for example, in a robot or the like, it is necessary to allow a sufficient wire length so as not to hinder the movement of the joints, and this is a practical problem in designing for miniaturization and weight reduction. Become.
　特に、最先端のヒューマノイド型ロボットや、人体に装着して筋力を補助するパワーアシスト装置等の用途においては、多自由度関節を経由して末端のモータを動かすための電線や、末端に配置された各種センサーからの電気信号を伝送するための電線が多数配線されている。そして、多自由度関節におけるこれらの配線の自由度を高めるために、伸縮可能に構成された電線に対する要求が高まっている。 Especially in applications such as state-of-the-art humanoid robots and power assist devices that are attached to the human body to assist muscular strength, electric wires for moving the end motor via a multi-degree-of-freedom joint, Many wires for transmitting electrical signals from various sensors are wired. And in order to raise the freedom degree of these wiring in a multi-degree-of-freedom joint, the request | requirement with respect to the electric wire comprised so that expansion-contraction is possible is increasing.
　一方、近年、産業用ロボットとしてアームロボットが多く使用されている。この種のアームロボットでは、ロボットアームの先端側に取り付けられているエンドエフェクタ（人体で言うところの手に相当）やロボットアームの関節部の駆動方式によっては、ロボットアームの根本側から先端側へかけて、電気ケーブル以外に、空圧印加用のエアホースや油圧ホースを配線する必要が生じることがある。かかるケーブルやホース類を関節部に配線した場合、ケーブルの折れ曲がりや断線を生じるおそれがある。そのため、ケーブルやホース類をロボットアーム類の関節部よりも基端寄りの位置で一旦外側に出し、関節部の外側空間にケーブルを配置し、関節部よりも先端寄りとなる位置で再びアーム内に導入するといった配線手法が採用されている。しかしながら、ロボットアームの外側空間にケーブルを配置する手法では、ロボットアームの関節部周囲にケーブルを弛ませるための空間が必要になる。 On the other hand, in recent years, arm robots are often used as industrial robots. In this type of arm robot, depending on the end effector attached to the tip side of the robot arm (equivalent to a hand in the human body) or the driving method of the joint part of the robot arm, from the base side to the tip side of the robot arm In addition to the electric cable, it may be necessary to wire an air hose or a hydraulic hose for applying air pressure. When such cables and hoses are wired to the joints, the cables may be bent or disconnected. For this reason, the cables and hoses are temporarily extended outward at positions closer to the base end than the joints of the robot arms, and the cables are arranged in the outer space of the joints, and again inside the arm at positions closer to the tip than the joints. A wiring method such as introduction into the network is adopted. However, in the method of arranging the cable in the outer space of the robot arm, a space for loosening the cable is required around the joint portion of the robot arm.
　また、たとえば特許文献１には、ロボットアームの関節部における関節回転中心位置に支持棒を設け、その支持棒にケーブルを巻回し、そのケーブルが予め巻かれた支持棒をロボットアームの内部に収納することで、ケーブルの折れ曲がりや断線を防止する構造が開示されている。しかしながら、支持棒を別途設けることによる重量増加による機能低下（動作速度・精度等）が生じるおそれがある。その機能低下を補うためにスペックの高いモーター等を用いたり、必要部材が増える場合もあるが、その場合には、製造コストが増加してしまう。さらにはケーブルの収納部の構造が複雑になるため、ロボットアーム組み立て時のケーブルの配線、メンテナンス等で分解し、ケーブルを取り出し、交換する際に非常に煩雑になるという問題がある。このことから、ロボットアームにおいても、このような問題を回避できる伸縮可能な電気伝送部材に対する要求が高まっている。 Further, for example, in Patent Document 1, a support rod is provided at the joint rotation center position in the joint portion of the robot arm, a cable is wound around the support rod, and the support rod on which the cable is wound is stored in the robot arm. Thus, a structure that prevents the cable from being bent or disconnected is disclosed. However, there is a possibility that functional deterioration (operation speed, accuracy, etc.) due to weight increase due to the separate provision of the support rod may occur. In some cases, a high-spec motor or the like is used in order to compensate for the deterioration of the function or the number of necessary members increases. In this case, the manufacturing cost increases. Furthermore, since the structure of the cable storage portion becomes complicated, there is a problem that it becomes very complicated when the cable is taken out and replaced when it is disassembled during wiring and maintenance of the robot arm during assembly. For this reason, even in the robot arm, there is an increasing demand for a telescopic electric transmission member that can avoid such a problem.
　そのような電気伝送部材に対する要求に対応するものとしては、たとえば特許文献２および特許文献３に開示の技術がある。かかる特許文献２、３には、湾曲形状部を交互に配置した、いわゆるプリーツ状に成形加工した伸縮可能なフレキシブルプリント配線板および成形方法が開示されている。特許文献２、３に開示の伸縮可能なフレキシブルプリント配線板はＬＣＰ（Liquid Crystal Polymer）等の熱可塑性樹脂を用いており、樹脂の軟化温度よりも数十℃～１００℃程度低い温度で３０分から６０分程度加熱することで、成形型と略同形状に成形している。 For example, Patent Document 2 and Patent Document 3 disclose techniques that meet the demand for such an electric transmission member. Patent Documents 2 and 3 disclose a flexible printed wiring board that can be stretched and formed into a so-called pleated shape in which curved portions are alternately arranged, and a forming method. The stretchable flexible printed wiring board disclosed in Patent Documents 2 and 3 uses a thermoplastic resin such as LCP (Liquid Crystal Polymer), and is 30 minutes lower than the softening temperature of the resin by several tens of degrees Celsius to 100 degrees Celsius. By heating for about 60 minutes, it is molded in substantially the same shape as the mold.
　ここで、特許文献２には、金型内部に先端に所望のＲが形成された板をフレキシブルプリント配線板が通せる間隔で複数個所配置し、一定テンションを加えながら金型内部にフレキシブルプリント配線板を通すことで、加熱成形する方法が記載されている。 Here, in Patent Document 2, a plurality of boards having a desired R formed at the tip inside the mold are arranged at intervals at which the flexible printed wiring board can pass, and the flexible printed wiring is placed inside the mold while applying a certain tension. A method of thermoforming by passing a plate is described.
　また、特許文献３には、治具に所望のＲで形成されたピンをフレキシブルプリント配線板が通せる間隔で複数本配置し、その治具へ一定テンションを加えながらフレキシブルプリント配線板を通すことで、加熱成形する方法が記載されている。 Further, in Patent Document 3, a plurality of pins formed with a desired R in a jig are arranged at intervals at which the flexible printed wiring board can pass, and the flexible printed wiring board is passed through the jig while applying a certain tension. And a method of thermoforming is described.
特開平８－５７７９２号公報Japanese Patent Laid-Open No. 8-57772 特開２０１１－１３４８８４号公報（図２、段落００４４等）JP 2011-134484 A (FIG. 2, paragraph 0044, etc.) 特開２０１１－２３３８２２号公報（図４、段落００４９等）Japanese Patent Laying-Open No. 2011-233822 (FIG. 4, paragraph 0049, etc.)
　ところで、特許文献２に開示の方法では、金型に接触している面積が大きいので、フレキシブルプリント配線板と金型間での摩擦が大きくなり、一定テンションでの引っ張りは困難となる。そのため、成形形状の安定化が難しい。また、フレキシブルプリント配線板を金型から取り外す際にも、上述の摩擦の大きさが作業性を悪化させてしまう。また、フレキシブルプリント配線板の成形が必要な部位に対し、不要な個所にも金型の板があるため、熱容量が大きくなる。したがって、成形に必要な温度まで上昇させることが困難である。 By the way, in the method disclosed in Patent Document 2, since the area in contact with the mold is large, the friction between the flexible printed wiring board and the mold is increased, and it is difficult to pull at a constant tension. Therefore, it is difficult to stabilize the molded shape. Moreover, when removing a flexible printed wiring board from a metal mold | die, the magnitude | size of the above-mentioned friction will deteriorate workability | operativity. In addition, the heat capacity is increased because there is a mold plate at an unnecessary portion with respect to a portion where the flexible printed wiring board needs to be molded. Therefore, it is difficult to raise the temperature required for molding.
　また、特許文献３に開示の方法では、特許文献２に開示の板状の金型を用いる場合よりは治具をセットする際の作業性は改善され、しかも摩擦の影響は少ない。しかしながら、この方法においても、フレキシブルプリント配線板と治具間での摩擦が大きく、一定テンションでの引っ張りは困難であり、それゆえ成形形状の安定化が難しい。これはピンの数が増えたり、異なるＲのピンが配置された場合に、太いピンのほうが相対的に摩擦が大きくなるため、より顕著になる。さらに、固定されたピンの間にフレキシブルプリント配線板を通していくこと自体が煩雑であり、ピン間が狭く、ピン数が多い治具に対しては、非常に作業性が悪い。 Further, in the method disclosed in Patent Document 3, the workability when setting a jig is improved and the influence of friction is less than that in the case of using the plate-shaped mold disclosed in Patent Document 2. However, even in this method, the friction between the flexible printed wiring board and the jig is large, and it is difficult to pull with a constant tension. Therefore, it is difficult to stabilize the molded shape. This is more noticeable when the number of pins increases or when different R pins are arranged, since the thicker pins have relatively higher friction. Furthermore, passing the flexible printed wiring board between the fixed pins is complicated, and the workability is very poor for a jig having a narrow space between pins and a large number of pins.

FIG. 1 is a front sectional view showing an example of the configuration of a flexible printed circuit board FA (or a molded flexible printed circuit board FB) before molding. As shown in FIG. 1, the flexible printed boards FA and FB of the present embodiment have an insulating layer F1, a conductive pattern F2, and an adhesive layer F3. The insulating layer F1 uses a thermoplastic resin such as LCP (Liquid Crystal Polymer: LCP). Specifically, the front and back sides of the flexible printed boards FA and FB are covered with an insulating layer F1 of LCP, and a conductive pattern F2 is formed on any one of those insulating layers F1, and further covers the conductive pattern F2. Thus, the adhesive layer F3 is present. Then, another insulating layer F1 is bonded via the adhesive layer F3. That is, the conductive pattern F2 (conductive layer) is sandwiched between the pair of insulating layers F1. However, the conductive pattern F2 (conductive layer) is not limited to one layer, and two or more layers may be provided. In that case, an insulating layer for separating the conductive patterns F2 (conductive layer) from each other Is required.
　上記の成形前のフレキシブルプリント基板ＦＡを成形する場合、絶縁層Ｆ１を構成する樹脂の軟化温度よりも数十℃～１００℃程度低い温度で３０分から６０分程度加熱することで、成形型と略同形状に成形される。 When the above-described flexible printed circuit board FA is molded, it is heated approximately 30 to 60 minutes at a temperature several tens to 100 ° C. lower than the softening temperature of the resin constituting the insulating layer F1, so that it is substantially the same as the molding die. Molded into the same shape.

As shown in FIG. 2A, the flexible printed circuit board FA before molding is in a state where the bent portion FB1 is not formed.
　これに対して、成形後のフレキシブルプリント基板ＦＢは、複数の曲成部ＦＢ１を有している。この曲成部ＦＢ１は、後述する固定ピン２４や可動ピン２５の外周に倣うようにして形成されている。そのため、その曲成部ＦＢ１の曲率も、固定ピン２４や可動ピン２５に対応するものとなっている。以下、成形前のフレキシブルプリント基板ＦＡから、成形後のフレキシブルプリント基板ＦＢを製造するための基板製造用治具１０、基板製造装置１００およびフレキシブルプリント基板ＦＢの製造方法について、以下に説明する。 In contrast, the molded flexible printed circuit board FB has a plurality of bent portions FB1. The bent portion FB1 is formed so as to follow the outer periphery of a fixed pin 24 and a movable pin 25 described later. Therefore, the curvature of the bent portion FB 1 also corresponds to the fixed pin 24 and the movable pin 25. Hereinafter, a substrate manufacturing jig 10, a substrate manufacturing apparatus 100, and a manufacturing method of the flexible printed circuit board FB for manufacturing the flexible printed circuit board FB after forming from the flexible printed circuit board FA before forming will be described.

　図４および図５に示すように、基板製造用治具１０は、第１治具２０と、第２治具３０とを有している。第１治具２０は、たとえば直方体形状の本体部２１を有している。本体部２１には、位置決め凹部２２が設けられている。位置決め凹部２２は、第２治具３０の位置決め凸部３２（後述）が嵌め込まれる部分であり、それらの嵌合によって第２治具３０に対して第２治具３０の位置決めがなされる。本実施の形態では、位置決め凹部２２は、本体部２１の長手方向（Ｘ方向）の一端側（Ｘ２側）と他端側（Ｘ１側）にそれぞれ設けられている。しかしながら、第２治具３０に対する第１治具２０の位置決めが確実に行われるものであれば、位置決め凹部２２を設ける位置および個数は、適宜変更可能である。また、かかる位置決めを行うものであれば、本体部２１には位置決め凹部２２に代えて位置決め凸部を設け、第２治具３０の本体部３１に位置決め凹部を設ける構成等、他の構成を採用しても良い。 4 and 5, the substrate manufacturing jig 10 includes a first jig 20 and a second jig 30. The first jig 20 has, for example, a rectangular parallelepiped main body 21. The main body 21 is provided with a positioning recess 22. The positioning recess 22 is a portion into which a positioning protrusion 32 (described later) of the second jig 30 is fitted, and the second jig 30 is positioned with respect to the second jig 30 by the fitting. In the present embodiment, the positioning recess 22 is provided on one end side (X2 side) and the other end side (X1 side) in the longitudinal direction (X direction) of the main body 21. However, as long as the first jig 20 is reliably positioned with respect to the second jig 30, the position and number of the positioning recesses 22 can be changed as appropriate. In addition, as long as such positioning is performed, other configurations such as a configuration in which a positioning convex portion is provided in the main body portion 21 instead of the positioning concave portion 22 and a positioning concave portion is provided in the main body portion 31 of the second jig 30 are adopted. You may do it.
　なお、第１治具２０と第２治具３０の間の固定を、マグネットを用いて行う構成とすることも可能である。この場合、位置決め凹部２２に対して位置決め凸部３２を嵌合させると、第２治具３０に対して第１治具２０が固定される。しかしながら、マグネットによる固定ではなく、機械的なクランプやねじ止め等、その他の固定手段を用いて、第２治具３０に対して第１治具２０を固定しても良い。 It should be noted that the first jig 20 and the second jig 30 can be fixed using a magnet. In this case, when the positioning protrusion 32 is fitted to the positioning recess 22, the first jig 20 is fixed to the second jig 30. However, the first jig 20 may be fixed to the second jig 30 by using other fixing means such as mechanical clamping and screwing instead of fixing with a magnet.
　この本体部２１の長手方向（Ｘ方向）の一端側（Ｘ２側）には、先端固定部材２３が設けられている。先端固定部材２３は、第１保持手段に対応している。また、先端固定部材２３は、先端受部２３ａと、掛止ピン２３ｂとを有している。先端受部２３ａは、平板状に設けられていて、フレキシブルプリント基板ＦＡの先端側の裏面に接触する。また、掛止ピン２３ｂは、たとえば円柱状のピン形状に設けられている。 A tip fixing member 23 is provided on one end side (X2 side) in the longitudinal direction (X direction) of the main body 21. The tip fixing member 23 corresponds to the first holding means. The tip fixing member 23 includes a tip receiving portion 23a and a latch pin 23b. The tip receiving portion 23a is provided in a flat plate shape and contacts the back surface on the tip side of the flexible printed circuit board FA. Moreover, the latch pin 23b is provided, for example in the shape of a cylindrical pin.
　ここで、図６に示すように、フレキシブルプリント基板ＦＡの先端側には、後に切り落とす切り落とし部Ｆ４が設けられていて（図６では、後に切り落とすラインである切断ラインＦ６も示されている）、その切り落とし部Ｆ４には、孔部Ｆ５が設けられている。そのため、この孔部Ｆ５に掛止ピン２３ｂを差し込むことで、フレキシブルプリント基板ＦＡの先端側の位置決めがなされる構成となっている。 Here, as shown in FIG. 6, a cut-off portion F4 to be cut off later is provided on the front end side of the flexible printed circuit board FA (FIG. 6 also shows a cutting line F6 that is a line to be cut off later). The cut-off portion F4 is provided with a hole F5. For this reason, the front end side of the flexible printed circuit board FA is positioned by inserting the latch pin 23b into the hole F5.
　なお、先端固定部材２３の構成は、図３から図５に示す構成に限られるものではない。たとえば、掛止ピン２３ｂは、四角柱状を始めとする角柱形状、楕円柱状を始めとする円柱状であっても良く、その他の突起形状であっても良い。また、先端固定部材２３は、フレキシブルプリント基板ＦＡの先端側の位置決めを行えるものであれば、フレキシブルプリント基板ＦＡの切り落とし部Ｆ４をクランプしたり、切り落とし部Ｆ４を吸引保持する構成等、その他の構成であっても良い。 The configuration of the tip fixing member 23 is not limited to the configuration shown in FIGS. For example, the latch pin 23b may have a prismatic shape such as a quadrangular prism shape, a cylindrical shape such as an elliptical prism shape, or other protrusion shape. Further, as long as the distal end fixing member 23 can position the distal end side of the flexible printed circuit board FA, other configurations such as a configuration in which the cut-off portion F4 of the flexible printed circuit board FA is clamped or the cut-off portion F4 is sucked and held. It may be.
　また、図３から図５に示すように、本体部２１の一端側（Ｘ２側）であって先端固定部材２３よりも他端寄り（Ｘ１寄り）の部位には、支持部材に対応する固定ピン２４が設けられている。固定ピン２４は、本体部２１に固定されているピン部材であり、後述する可動ピン２５とは異なり、本体部２１に対して着脱不能に設けられている。ただし、固定ピン２４は、本体部２１に対して着脱可能としても良い。また、固定ピン２４は、本体部２１に対して着脱自在とするものの、可動ピン２５よりも抜け難い（簡単には可動しない）構成としても良い。 Further, as shown in FIGS. 3 to 5, a fixing pin corresponding to the support member is provided at one end side (X2 side) of the main body portion 21 and closer to the other end side (X1 side) than the tip fixing member 23. 24 is provided. The fixed pin 24 is a pin member that is fixed to the main body 21, and is provided so as to be detachable from the main body 21, unlike the movable pin 25 described later. However, the fixing pin 24 may be detachable from the main body 21. Further, although the fixed pin 24 is detachable from the main body 21, the fixed pin 24 may be configured to be more difficult to be removed (not easily movable) than the movable pin 25.
　また、固定ピン２４の湾曲した外周面の曲率は、成形するフレキシブルプリント基板ＦＢの湾曲部分の曲率に対応した曲率となっている。また、固定ピン２４の上面は、先端固定部材２３の先端受部２３ａと略面一に設けられている。すなわち、先端受部２３ａの上面を通ると共に長手方向（Ｘ方向）に平行な搬送ラインＬは、先端受部２３ａの上面側に接触する。また、固定ピン２４は、本体部２１の側面に対して垂直方向に延伸していて、しかも固定ピン２４の長さは、フレキシブルプリント基板ＦＡの幅方向（Ｙ方向）の長さよりも長くなるように設けられている。 Further, the curvature of the curved outer peripheral surface of the fixing pin 24 is a curvature corresponding to the curvature of the curved portion of the flexible printed circuit board FB to be molded. Further, the upper surface of the fixing pin 24 is provided substantially flush with the tip receiving portion 23 a of the tip fixing member 23. That is, the conveyance line L passing through the upper surface of the tip receiving portion 23a and parallel to the longitudinal direction (X direction) is in contact with the upper surface side of the tip receiving portion 23a. The fixing pin 24 extends in a direction perpendicular to the side surface of the main body 21 and the length of the fixing pin 24 is longer than the length in the width direction (Y direction) of the flexible printed circuit board FA. Is provided.
　また、本体部２１には、複数本の可動ピン２５（支持部材に対応）が配置可能となっている。本実施の形態では、可動ピン２５は、本体部２１に対して着脱自在に設けられている。そのような着脱を可能とするために、本体部２１には、差込孔２１１が設けられている。差込孔２１１は、本体部２１の幅方向（Ｙ方向）を貫通するように設けられている。また、差込孔２１１は、可動ピン２５を差し込むことができるものの、その可動ピン２５の差込孔２１１への差込後に、可動ピン２５がガタ付かない程度の公差を有して形成されている。 Further, a plurality of movable pins 25 (corresponding to support members) can be arranged on the main body 21. In the present embodiment, the movable pin 25 is detachably attached to the main body portion 21. In order to enable such attachment and detachment, the main body portion 21 is provided with an insertion hole 211. The insertion hole 211 is provided so as to penetrate the width direction (Y direction) of the main body portion 21. In addition, the insertion hole 211 can be inserted with the movable pin 25, but has a tolerance that the movable pin 25 does not rattle after the insertion of the movable pin 25 into the insertion hole 211. Yes.
　この差込孔２１１に差し込まれる可動ピン２５は、図７に示すように、ピン部２５１と鍔部２５２を有している。ピン部２５１は、同一径のピン形状部分であり、鍔部２５２はピン部２５１よりも大径に設けられている部分である。そのため、差込孔２１１にピン部２５１の先端側から差し込む場合、鍔部２５２は差込孔２１１を通過できず、可動ピン２５が第１治具２０に係止される。なお、鍔部２５２が本体部２１に接触する場合、ピン部２５１はフレキシブルプリント基板ＦＡの幅よりも長く本体部２１からＹ１方向に突出する。 The movable pin 25 inserted into the insertion hole 211 has a pin portion 251 and a flange portion 252 as shown in FIG. The pin portion 251 is a pin-shaped portion having the same diameter, and the flange portion 252 is a portion provided with a larger diameter than the pin portion 251. Therefore, when inserting into the insertion hole 211 from the front end side of the pin part 251, the flange part 252 cannot pass through the insertion hole 211, and the movable pin 25 is locked to the first jig 20. In addition, when the collar part 252 contacts the main body part 21, the pin part 251 is longer than the width of the flexible printed circuit board FA and protrudes from the main body part 21 in the Y1 direction.
　また、図３から図５に示す構成では、差込孔２１１は、幅方向（Ｙ方向）の全体に亘って孔径が同一となるように設けられている。しかしながら、差込孔２１１の少なくとも一部がテーパ孔等、孔径が同一ではない構成としても良い。たとえば、図８に示すように、差込孔２１１のうち可動ピン２５の差し込みの先端側（Ｙ２側）から後端側（Ｙ１側；第２治具３０側）の途中部位までは同一径のストレート孔２１２とし、その途中部位から後端側（Ｙ２側）に向かうにつれて徐々に孔径が大きくなるテーパ孔２１３としても良い。また、差込孔２１１の全体をテーパ孔としても良い。 Further, in the configuration shown in FIGS. 3 to 5, the insertion hole 211 is provided so that the hole diameter is the same throughout the width direction (Y direction). However, at least a part of the insertion hole 211 may be configured such that the hole diameter is not the same, such as a tapered hole. For example, as shown in FIG. 8, the insertion hole 211 has the same diameter from the front end side (Y2 side) of the insertion of the movable pin 25 to the middle part of the rear end side (Y1 side; second jig 30 side). The straight hole 212 may be a tapered hole 213 whose diameter gradually increases from the midway portion toward the rear end side (Y2 side). Further, the entire insertion hole 211 may be a tapered hole.
　以上のような差込孔２１１は、図３および図４に示す構成では、合計９個設けられている。しかしながら、この差込孔２１１の個数は、幾つであっても良い。なお、差込孔２１１は、搬送ラインＬを挟んで下方側（Ｚ２側）に位置するものと、上方側（Ｚ１側）に位置するものとが交互に存在している。以下の説明では、必要に応じて、長手方向（Ｘ方向）に沿って、最も一端側（Ｘ２側）の差込孔２１１を差込孔２１１ａとし、以後、他端側（Ｘ１側）に向かうにつれて順番に差込孔２１１ｂ～２１１ｉとする。なお、固定ピン２４の上面側にフレキシブルプリント基板ＦＡが接触する場合、長手方向（Ｘ方向）の最も一端側（Ｘ２側）の差込孔２１１（差込孔２１１ａ）は、搬送ラインＬよりも下方側（Ｚ２側）に位置している。 In the configuration shown in FIGS. 3 and 4, a total of nine insertion holes 211 as described above are provided. However, the number of the insertion holes 211 may be any number. The insertion holes 211 are alternately located on the lower side (Z2 side) with the conveyance line L in between and on the upper side (Z1 side). In the following description, if necessary, the insertion hole 211 on the most end side (X2 side) is referred to as the insertion hole 211a along the longitudinal direction (X direction), and thereafter the other end side (X1 side). Accordingly, the insertion holes 211b to 211i are sequentially set. When the flexible printed circuit board FA is in contact with the upper surface side of the fixing pin 24, the insertion hole 211 (insertion hole 211a) on the most end side (X2 side) in the longitudinal direction (X direction) is more than the transport line L. It is located on the lower side (Z2 side).
　また、以下の説明では、必要に応じて、差込孔２１１ａ～２１１ｉにそれぞれ差し込まれる可動ピン２５を、可動ピン２５ａ～２５ｉと称呼する。 In the following description, the movable pins 25 that are respectively inserted into the insertion holes 211a to 211i are referred to as movable pins 25a to 25i as necessary.
　また、図３から図５に示すように、差込孔２１１ｉよりも長手方向（Ｘ方向）の他端側（Ｘ１側）の部位には、第２保持手段に対応する終端固定部材２６が設けられている。終端固定部材２６は、後述する後端保持部材２００との間でフレキシブルプリント基板ＦＡを挟み込み、そのフレキシブルプリント基板ＦＡの終端側（Ｘ１側の端部）を固定する部分である。この終端固定部材２６は、先端受部２３ａと同様な平板状に設けられていて、フレキシブルプリント基板ＦＡの終端側の裏面に接触する。なお、終端固定部材２６と共に後端保持部材２００も第２保持手段に対応するものとしても良い。 Further, as shown in FIGS. 3 to 5, a terminal fixing member 26 corresponding to the second holding means is provided in a portion on the other end side (X1 side) in the longitudinal direction (X direction) from the insertion hole 211i. It has been. The terminal fixing member 26 is a part that sandwiches the flexible printed circuit board FA with a rear end holding member 200 described later and fixes the terminal side (X1 side end) of the flexible printed circuit board FA. The end fixing member 26 is provided in a flat plate shape similar to the tip receiving portion 23a, and contacts the back surface on the end side of the flexible printed circuit board FA. The rear end holding member 200 together with the end fixing member 26 may correspond to the second holding means.
　なお、図示は省略するが、フレキシブルプリント基板ＦＡの後端側にも、上述の切り落とし部Ｆ４と同様の切り落とし部（ただし孔部Ｆ５がないものとしても良い）が存在している。また、終端固定部材２６の構成は、先端固定部材２３と同様に、図３から図５に示す構成に限られるものではなく、その他の構成を採用しても良い。 In addition, although illustration is abbreviate | omitted, the cutout part (however, it is good also as what does not have the hole part F5) similar to the above-mentioned cutout part F4 exists also in the rear-end side of the flexible printed circuit board FA. Further, the configuration of the terminal fixing member 26 is not limited to the configuration shown in FIGS. 3 to 5 as in the tip fixing member 23, and other configurations may be adopted.
　次に、第２治具３０について説明する。第２治具３０は、基板製造装置１００に取り付けられる部材であると共に、第１治具２０が取り付けられる部材である（図４および図５参照）。すなわち、第２治具３０を介して、第１治具２０が基板製造装置１００に取り付けられる。そのため、第２治具３０は、側面視したときの形状が本体部２１と同等の大きさとなる直方体形状の本体部３１を有している。 Next, the second jig 30 will be described. The second jig 30 is a member attached to the substrate manufacturing apparatus 100 and a member to which the first jig 20 is attached (see FIGS. 4 and 5). That is, the first jig 20 is attached to the substrate manufacturing apparatus 100 via the second jig 30. Therefore, the second jig 30 has a rectangular parallelepiped main body 31 whose shape when viewed from the side is the same size as the main body 21.
　図４および図５に示すように、本体部３１には、位置決め凸部３２が設けられている。位置決め凸部３２は、上述した位置決め凹部２２に差し込まれることで、第２治具３０に対する第１治具２０の位置決めを行うための部分である。そのため、位置決め凸部３２は、位置決め凹部２２に対応する位置に設けられている。 As shown in FIGS. 4 and 5, the main body 31 is provided with a positioning convex portion 32. The positioning convex portion 32 is a portion for positioning the first jig 20 with respect to the second jig 30 by being inserted into the positioning concave portion 22 described above. Therefore, the positioning convex portion 32 is provided at a position corresponding to the positioning concave portion 22.
　また、本体部３１には、貫通孔であるスリーブ３３が設けられている。スリーブ３３は、第２治具３０に対して第１治具２０が固定された場合に、差込孔２１１と同軸となる位置に設けられている。そのため、スリーブ３３は、差込孔２１１と同数設けられている。ここで、スリーブ３３は、差込孔２１１よりも孔径が大きく設けられている。具体的には、スリーブ３３は、鍔部２５２が挿通可能な程度の孔径に設けられている。そのため、可動ピン２５をスリーブ３３を差し込むと、その可動ピン２５のピン部２５１がスリーブ３３を通過する。そして、可動ピン２５の鍔部２５２がスリーブ３３に位置する状態で、ピン部２５１を差込孔２１１に位置させることが可能となる。そのため、スリーブ３３は、可動ピン２５をガイドするガイドとしての機能を有している。 The main body 31 is provided with a sleeve 33 which is a through hole. The sleeve 33 is provided at a position that is coaxial with the insertion hole 211 when the first jig 20 is fixed to the second jig 30. Therefore, the same number of sleeves 33 as the insertion holes 211 are provided. Here, the sleeve 33 is provided with a larger hole diameter than the insertion hole 211. Specifically, the sleeve 33 is provided with a hole diameter such that the flange portion 252 can be inserted. Therefore, when the sleeve 33 is inserted into the movable pin 25, the pin portion 251 of the movable pin 25 passes through the sleeve 33. In addition, the pin portion 251 can be positioned in the insertion hole 211 in a state where the flange portion 252 of the movable pin 25 is positioned on the sleeve 33. Therefore, the sleeve 33 has a function as a guide for guiding the movable pin 25.
＜基板製造装置１００の構成について＞
　続いて、基板製造装置１００の構成について以下に説明する。図９は、基板製造装置１００の概略構成を示すブロック図である。この図９に示すように、基板製造装置１００は、制御部１１０、治具挟持機構１２０、治具スライダ１３０、ピン押し出し機構１４０、トルクローラ接離機構１５０、フリーローラ接離機構１６０、ローラ駆動機構１７０、先端保持機構１８０、側面押当機構１９０を備えている。 <About Configuration of Substrate Manufacturing Apparatus 100>
Next, the configuration of the substrate manufacturing apparatus 100 will be described below. FIG. 9 is a block diagram illustrating a schematic configuration of the substrate manufacturing apparatus 100. As shown in FIG. 9, the substrate manufacturing apparatus 100 includes a control unit 110, a jig clamping mechanism 120, a jig slider 130, a pin pushing mechanism 140, a torque roller contact / separation mechanism 150, a free roller contact / separation mechanism 160, and a roller drive. A mechanism 170, a tip holding mechanism 180, and a side surface pressing mechanism 190 are provided.
　これらのうち、制御部１１０は、各駆動部位の制御を司る部分であり、たとえばＣＰＵ（Central Processing Unit）、ＲＯＭ（Read Only Memory）やＲＡＭ（Random Access Memory）、不揮発性メモリ等のメモリを備え、メモリには各種制御のためのデータやプログラムが記憶されている。 Of these, the control unit 110 is a part that controls each drive part, and includes a memory such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a nonvolatile memory. The memory stores data and programs for various controls.
　また、治具挟持機構１２０は、たとえば一対の挟持部材１２１を有していて、この一対の挟持部材１２１によって第２治具３０を挟持する。かかる治具挟持機構１２０での第２治具３０の挟持により、第２治具３０が基板製造装置１００に固定される。なお、治具挟持機構１２０は、手動により挟持する構成としても良く、モータ等の駆動源を用いて自動的に挟持する構成としても良い。 Further, the jig clamping mechanism 120 includes, for example, a pair of clamping members 121, and the second jig 30 is clamped by the pair of clamping members 121. By holding the second jig 30 by the jig holding mechanism 120, the second jig 30 is fixed to the substrate manufacturing apparatus 100. The jig clamping mechanism 120 may be configured to be manually clamped, or may be configured to be automatically clamped using a drive source such as a motor.
　また、治具スライダ１３０は、第２駆動手段に対応するスライドモータ１３１を備え、そのスライドモータ１３１の駆動によって基板製造用治具１０をスライドさせる部分である。かかる治具スライダ１３０で基板製造用治具１０をスライドさせる場合、後述するトルクローラ１５１やフリーローラ１６１等に対して、基板製造用治具１０をスライドさせることができる。 The jig slider 130 includes a slide motor 131 corresponding to the second driving means, and is a part that slides the board manufacturing jig 10 by driving the slide motor 131. When the substrate manufacturing jig 10 is slid with the jig slider 130, the substrate manufacturing jig 10 can be slid with respect to a torque roller 151, a free roller 161, and the like, which will be described later.
　図９では、治具スライダ１３０の一例として、ベルト１３２を用いる場合が例示されており、そのベルト１３２の一部に挟持部材１２１等の部位が固定されている。図９は模式図であるためベルト１３２が短い状態で図示されているが、ベルト１３２は基板製造用治具１０を十分にスライド可能な長さに設けられている。なお、治具スライダ１３０を構成する要素として、送りねじ等、ベルト１３２以外の構成を用いても良い。 FIG. 9 illustrates a case where a belt 132 is used as an example of the jig slider 130, and a part such as the clamping member 121 is fixed to a part of the belt 132. Since FIG. 9 is a schematic view, the belt 132 is illustrated in a short state, but the belt 132 is provided with a length that allows the substrate manufacturing jig 10 to be sufficiently slid. In addition, you may use structures other than the belt 132, such as a lead screw, as an element which comprises the jig | tool slider 130. FIG.
　また、ピン押し出し機構１４０は、エアシリンダ１４１を備え、このエアシリンダ１４１の作動によってスリーブ３３を介して可動ピン２５を差込孔２１１に向けて押し出す機構である。なお、ピン押し出し機構１４０には、エアシリンダ１４１を移動させる移動機構（図示省略）も設けられており、その移動機構の作動により、それぞれの差込孔２１１に可動ピン２５を順次差し込むことを可能としている。 Further, the pin push-out mechanism 140 includes an air cylinder 141 and is a mechanism that pushes the movable pin 25 toward the insertion hole 211 through the sleeve 33 by the operation of the air cylinder 141. The pin pushing mechanism 140 is also provided with a moving mechanism (not shown) for moving the air cylinder 141, and the movable pin 25 can be sequentially inserted into each insertion hole 211 by the operation of the moving mechanism. It is said.
　また、トルクローラ接離機構１５０は、トルクローラ１５１と、エアシリンダ１５２と、不図示の付勢手段を備えている。トルクローラ１５１には、駆動ローラ１５１ａと従動ローラ１５１ｂとが設けられていて、それらが上下方向に沿って配置されている。そして、エアシリンダ１５２が作動していない状態では、付勢手段の作用によって駆動ローラ１５１ａと従動ローラ１５１ｂとが上下方向で離れているが、エアシリンダ１５２が作動すると駆動ローラ１５１ａと従動ローラ１５１ｂとが互いに接近した閉じ状態となり、フレキシブルプリント基板ＦＡを所定の押圧力で挟むことが可能となる。 The torque roller contact / separation mechanism 150 includes a torque roller 151, an air cylinder 152, and an urging means (not shown). The torque roller 151 is provided with a driving roller 151a and a driven roller 151b, which are arranged along the vertical direction. When the air cylinder 152 is not in operation, the driving roller 151a and the driven roller 151b are separated in the vertical direction by the action of the urging means, but when the air cylinder 152 is operated, the driving roller 151a and the driven roller 151b are Are close to each other and the flexible printed circuit board FA can be sandwiched with a predetermined pressing force.
　また、フリーローラ接離機構１６０は、フリーローラ１６１と、エアシリンダ１６２と、不図示の付勢手段を備えている。フリーローラ１６１は、一対の従動ローラ１６１ａ，１６１ｂを有していて、それらが上下方向に沿って配置されている。そして、エアシリンダ１６２が作動していない状態では、付勢手段の作用によって従動ローラ１６１ａ，１６１ｂが上下方向で互いに離れているが、エアシリンダ１６２が作動すると従動ローラ１６１ａ，１６１ｂが互いに接近した閉じ状態となり、フレキシブルプリント基板ＦＡを所定の押圧力で挟むことが可能となる。なお、フリーローラ１６１は、トルクローラ１５１よりも長手方向（Ｘ方向）の一端側（Ｘ２側）に位置している。 The free roller contact / separation mechanism 160 includes a free roller 161, an air cylinder 162, and an urging means (not shown). The free roller 161 has a pair of driven rollers 161a and 161b, which are arranged along the vertical direction. When the air cylinder 162 is not in operation, the driven rollers 161a and 161b are separated from each other in the vertical direction by the action of the urging means. However, when the air cylinder 162 is operated, the driven rollers 161a and 161b are closed close to each other. Thus, the flexible printed circuit board FA can be sandwiched with a predetermined pressing force. The free roller 161 is located on one end side (X2 side) in the longitudinal direction (X direction) with respect to the torque roller 151.
　ローラ駆動機構１７０は、駆動モータ１７１を備えている。そして、駆動モータ１７１の作動により、駆動ローラ１５１ａを駆動させることができる。そのため、駆動ローラ１５１ａと従動ローラ１５１ｂとでフレキシブルプリント基板ＦＡを挟み込んだ状態で駆動ローラ１５１ａを駆動させることで、フレキシブルプリント基板ＦＡを送ることができ、他端側（Ｘ１側；図９の右側）に送る場合には、フレキシブルプリント基板ＦＡにテンションを付与することができる。 The roller drive mechanism 170 includes a drive motor 171. The drive roller 151 a can be driven by the operation of the drive motor 171. Therefore, the flexible printed circuit board FA can be sent by driving the driving roller 151a with the flexible printed circuit board FA sandwiched between the driving roller 151a and the driven roller 151b, and the other side (X1 side; right side of FIG. 9). ), Tension can be applied to the flexible printed circuit board FA.
　また、先端保持機構１８０は、先端挟持部材１８１と、エアシリンダ１８２を有している。先端挟持部材１８１は、図９に示すように側面視した形状が略Ｌ字形状に設けられていて、先端固定部材２３の先端側に当接する。そのような当接を可能とするため、先端側当接部１８１ａは、上面当接部１８１ｂよりも上下方向（Ｚ方向）に長く設けられている。また、先端挟持部材１８１の上面当接部１８１ｂは、切り落とし部Ｆ４の上面側に当接して、先端受部２３ａとの間で切り落とし部Ｆ４を挟み込む。かかる動作を実現するために、先端挟持部材１８１は、エアシリンダ１８２（第１駆動手段に対応）の作動によって上下方向（Ｚ方向）に移動可能としている。それにより、フレキシブルプリント基板ＦＡの先端側が確実に固定される。なお、上面当接部１８１ｂには、図示を省略する凹部が設けられていて、掛止ピン２３ｂを入り込ませることを可能としている。 The tip holding mechanism 180 has a tip clamping member 181 and an air cylinder 182. As shown in FIG. 9, the tip clamping member 181 is provided in a substantially L shape when viewed from the side, and abuts against the tip side of the tip fixing member 23. In order to enable such contact, the distal end side contact portion 181a is provided longer in the vertical direction (Z direction) than the upper surface contact portion 181b. Further, the upper surface contact portion 181b of the tip clamping member 181 contacts the upper surface side of the cut-off portion F4, and sandwiches the cut-off portion F4 with the tip receiving portion 23a. In order to realize such an operation, the tip clamping member 181 is movable in the vertical direction (Z direction) by the operation of the air cylinder 182 (corresponding to the first driving means). Thereby, the front end side of the flexible printed circuit board FA is securely fixed. In addition, the upper surface contact portion 181b is provided with a concave portion (not shown) so that the latch pin 23b can be inserted.
　また、側面押当機構１９０は、側面押当部材１９１と、エアシリンダ１９２を有している。側面押当部材１９１は、本体部２１の側面に当接する側面当接部１９１ａを有している。かかる側面当接部１９１ａがフレキシブルプリント基板ＦＡのＹ２側の側面に当接すると、フレキシブルプリント基板ＦＡのスキュー方向（角度方向）の調整を行うことができる。そのような動作を実現するために、側面押当部材１９１は、エアシリンダ１９２の作動によって、幅方向（Ｙ方向）に移動可能としている。 Further, the side surface pressing mechanism 190 has a side surface pressing member 191 and an air cylinder 192. The side pressing member 191 has a side contact portion 191 a that contacts the side surface of the main body portion 21. When the side surface contact portion 191a contacts the Y2 side surface of the flexible printed circuit board FA, the skew direction (angular direction) of the flexible printed circuit board FA can be adjusted. In order to realize such an operation, the side pressing member 191 is movable in the width direction (Y direction) by the operation of the air cylinder 192.
　なお、基板製造装置１００は、後端保持部材２００を備える構成としても良いが、後端保持部材２００は基板製造装置１００とは別の構成としても良い。この後端保持部材２００は、たとえば板状の部材であり、後端側の切り落とし部Ｆ４の上面側に当接する。それにより、終端固定部材２６との間で切り落とし部Ｆ４を挟み込み、フレキシブルプリント基板ＦＡの後端側を確実に固定する。このようなフレキシブルプリント基板ＦＡの固定を実現するために、後端保持部材２００は、磁力によって終端固定部材２６に取り付けられる構成としても良いが、たとえばクランプその他の手段によって終端固定部材２６に取り付けられる構成としても良い。 The substrate manufacturing apparatus 100 may be configured to include the rear end holding member 200, but the rear end holding member 200 may be configured differently from the substrate manufacturing apparatus 100. The rear end holding member 200 is, for example, a plate-like member, and abuts on the upper surface side of the rear end side cut-off portion F4. Accordingly, the cut-off portion F4 is sandwiched between the terminal fixing member 26 and the rear end side of the flexible printed circuit board FA is securely fixed. In order to realize such fixation of the flexible printed circuit board FA, the rear end holding member 200 may be configured to be attached to the terminal fixing member 26 by magnetic force, but is attached to the terminal fixing member 26 by, for example, a clamp or other means. It is good also as a structure.
＜フレキシブルプリント基板ＦＢの製造方法について＞
　続いて、フレキシブルプリント基板ＦＢの製造方法について、以下に説明する。なお、以下の説明においては、第１工程から第１０工程について順次記載するが、各実施の形態におけるフレキシブルプリント基板ＦＢの製造方法では、これ以外の種々の工程が存在していても良いのは勿論である。 <About manufacturing method of flexible printed circuit board FB>
Then, the manufacturing method of the flexible printed circuit board FB is demonstrated below. In the following description, the first step to the tenth step are sequentially described. However, in the method for manufacturing the flexible printed circuit board FB in each embodiment, various other steps may exist. Of course.
　（１）第１工程：フレキシブルプリント基板ＦＡのセット前（準備）
　まず最初に、図１０および図１１に示すように、フレキシブルプリント基板ＦＡをセットする前の準備を行う。そのために、治具挟持機構１２０を用いて第２治具３０を基板製造装置１００に固定する。その固定を容易に行えるようにするため、治具スライダ１３０は基板製造用治具１０をスライドさせて、基板製造装置１００の各部位と干渉しない位置（図１０および図１１では、基板製造装置１００に対して相対的に左側）に配置している。なお、この基板製造用治具１０のスライドでは、先端保持機構１８０もスライドするが、ピン押し出し機構１４０、トルクローラ接離機構１５０、フリーローラ接離機構１６０、側面押当機構１９０はスライドしない。 (1) First step: Before setting the flexible printed circuit board FA (preparation)
First, as shown in FIGS. 10 and 11, preparations are made before setting the flexible printed circuit board FA. For this purpose, the second jig 30 is fixed to the substrate manufacturing apparatus 100 using the jig clamping mechanism 120. In order to facilitate the fixing, the jig slider 130 slides the board manufacturing jig 10 so as not to interfere with each part of the board manufacturing apparatus 100 (in FIG. 10 and FIG. Relative to the left side). When the substrate manufacturing jig 10 slides, the tip holding mechanism 180 also slides, but the pin push-out mechanism 140, torque roller contact / separation mechanism 150, free roller contact / separation mechanism 160, and side surface pressing mechanism 190 do not slide.
　また、そのスライド後、図１１に示すように位置決め凸部３２を位置決め凹部２２に嵌め込むことで、第２治具３０に対して第１治具２０を取り付ける。かかる取り付け後、治具スライダ１３０は基板製造用治具１０を、先ほどとは逆側（図１０および図１１では、基板製造装置１００に対して相対的に右側）にスライドさせ、基板製造用治具１０を、フレキシブルプリント基板ＦＡの取り付けを行うためのポジションに移動させる。 Further, after the sliding, the first jig 20 is attached to the second jig 30 by fitting the positioning convex portion 32 into the positioning concave portion 22 as shown in FIG. After such attachment, the jig slider 130 slides the board manufacturing jig 10 to the opposite side (in FIG. 10 and FIG. 11, the right side relative to the board manufacturing apparatus 100), and the board manufacturing jig. The tool 10 is moved to a position for attaching the flexible printed circuit board FA.
　なお、この基板製造用治具１０の図１０および図１１における右側へのスライドに前後して、それぞれのスリーブ３３に可動ピン２５を差し込む。この差し込みは、本体部３１の手前側（Ｙ１側）の側面から、ピン部２５１が突出しない位置まで差し込むようにする。 Note that the movable pin 25 is inserted into each sleeve 33 before and after the substrate manufacturing jig 10 slides to the right in FIGS. 10 and 11. This insertion is performed from the front side (Y1 side) side of the main body 31 to a position where the pin portion 251 does not protrude.
　また、フレキシブルプリント基板ＦＡを第１治具２０に取り付ける際に、基板製造装置１００の各部位とフレキシブルプリント基板ＦＡとが干渉しないようにしている。そのため、先端保持機構１８０の先端挟持部材１８１は、上方側（Ｚ１側）に退避した状態となっている。同様に、側面押当機構１９０の側面押当部材１９１も手前側（Ｙ１側）に退避すると共に、後端保持部材２００も上方側（Ｚ１側）に退避している。また、トルクローラ１５１の駆動ローラ１５１ａと従動ローラ１５１ｂとは上下方向で互いに離間した状態となっている。また、フリーローラ１６１の従動ローラ１６１ａ，１６１ｂも上下方向で互いに離間した状態となっている。 Further, when the flexible printed circuit board FA is attached to the first jig 20, each part of the substrate manufacturing apparatus 100 and the flexible printed circuit board FA are prevented from interfering with each other. Therefore, the tip clamping member 181 of the tip holding mechanism 180 is in a state of being retracted upward (Z1 side). Similarly, the side surface pressing member 191 of the side surface pressing mechanism 190 is also retracted to the front side (Y1 side), and the rear end holding member 200 is also retracted to the upper side (Z1 side). Further, the driving roller 151a and the driven roller 151b of the torque roller 151 are separated from each other in the vertical direction. Further, the driven rollers 161a and 161b of the free roller 161 are also separated from each other in the vertical direction.
　なお、フレキシブルプリント基板ＦＡを次々に成形するために、フレキシブルプリント基板ＦＡのセット終了後は、第２治具３０から第１治具２０を取り外し、別の第１治具２０を第２治具３０に取り付ける。すなわち、１つの第２治具３０に対して、多数の第１治具２０が存在し、フレキシブルプリント基板ＦＡの第１治具２０への取り付けを、第１治具２０毎に順次行う構成としている。 In order to form the flexible printed circuit boards FA one after another, after the setting of the flexible printed circuit board FA is completed, the first jig 20 is removed from the second jig 30, and another first jig 20 is replaced with the second jig. Attach to 30. That is, there are a large number of first jigs 20 for one second jig 30, and the flexible printed circuit board FA is attached to the first jig 20 sequentially for each first jig 20. Yes.
　（２）第２工程：フレキシブルプリント基板ＦＡの先端側の取り付け
　次に、図１２および図１３に示すように、フレキシブルプリント基板ＦＡを第１治具２０に取り付ける。このとき、先端固定部材２３の掛止ピン２３ｂに、フレキシブルプリント基板ＦＡの孔部Ｆ５を差し込む（第１保持工程に対応）。それにより、フレキシブルプリント基板ＦＡの先端側の位置が定まる。この先端側の取り付け状態では、固定ピン２４の上面側にフレキシブルプリント基板ＦＡの下面が接触する状態とする。 (2) 2nd process: Attachment of the front end side of flexible printed circuit board FA Next, the flexible printed circuit board FA is attached to the 1st jig | tool 20, as shown in FIG. At this time, the hole F5 of the flexible printed circuit board FA is inserted into the latch pin 23b of the tip fixing member 23 (corresponding to the first holding step). Thereby, the position of the front end side of the flexible printed circuit board FA is determined. In the attached state on the distal end side, the lower surface of the flexible printed circuit board FA is in contact with the upper surface side of the fixing pin 24.
　（３）第３工程：フレキシブルプリント基板ＦＡの引っ張り開始
　次に、図１４および図１５に示すように、フレキシブルプリント基板ＦＡの後端側の側面を、側面押当機構１９０の側面押当部材１９１に押し当てる（スキュー調整工程に対応）。それにより、フレキシブルプリント基板ＦＡの回転方向の位置が定まる。そして、フレキシブルプリント基板ＦＡの回転方向の位置が定まるのに前後して、エアシリンダ１８２を作動させて先端挟持部材１８１を下方側に移動させて、先端受部２３ａと上面当接部１８１ｂとの間でフレキシブルプリント基板ＦＡを挟持する。 (3) Third Step: Start of Pulling of Flexible Printed Circuit Board FA Next, as shown in FIGS. 14 and 15, the side surface pressing member 191 of the side surface pressing mechanism 190 is connected to the side surface on the rear end side of the flexible printed circuit board FA. (It corresponds to the skew adjustment process). Thereby, the position of the flexible printed circuit board FA in the rotational direction is determined. Then, before and after the position of the flexible printed circuit board FA in the rotational direction is determined, the air cylinder 182 is operated to move the tip clamping member 181 downward, and the tip receiving portion 23a and the upper surface contact portion 181b are moved. The flexible printed circuit board FA is sandwiched between them.
　この挟持の後に、エアシリンダ１５２を作動させてトルクローラ１５１の駆動ローラ１５１ａと従動ローラ１５１ｂとを上下方向で互いに接近させ、フレキシブルプリント基板ＦＡを挟み込む。そして、この挟み込み後に、フレキシブルプリント基板ＦＡに対して送り方向（図１４における右方向）にテンションをかけるべく、ローラ駆動機構１７０の駆動モータ１７１を作動させて、駆動ローラ１５１ａをフレキシブルプリント基板ＦＡの送り方向に駆動する。 After this clamping, the air cylinder 152 is operated to bring the driving roller 151a and the driven roller 151b of the torque roller 151 close to each other in the vertical direction, thereby sandwiching the flexible printed circuit board FA. Then, after this clamping, the drive motor 171 of the roller drive mechanism 170 is operated to apply tension to the flexible printed circuit board FA in the feed direction (right direction in FIG. 14), and the drive roller 151a is moved to the flexible printed circuit board FA. Drive in the feed direction.
　また、この後に、エアシリンダ１６２を作動させてフリーローラ１６１の従動ローラ１６１ａ，１６１ｂを互いに上下方向で接近させて、フレキシブルプリント基板ＦＡを挟み込む。このように、フリーローラ１６１が閉じるよりも前に駆動モータ１７１を作動させることにより、先端固定部材２３とトルクローラ１５１の間でフレキシブルプリント基板ＦＡの弛みが一層良好に防止される。ただし、フリーローラ１６１によるフレキシブルプリント基板ＦＡの挟み込みは、駆動モータ１７１の作動よりも前としても良く、トルクローラ１５１によるフレキシブルプリント基板ＦＡの挟み込みよりも前としても良い。 After this, the air cylinder 162 is operated to bring the driven rollers 161a and 161b of the free roller 161 close to each other in the vertical direction, and the flexible printed circuit board FA is sandwiched. As described above, by operating the drive motor 171 before the free roller 161 is closed, loosening of the flexible printed circuit board FA between the front end fixing member 23 and the torque roller 151 is further prevented. However, the sandwiching of the flexible printed circuit board FA by the free roller 161 may be performed before the operation of the drive motor 171 or may be performed before the sandwiching of the flexible printed circuit board FA by the torque roller 151.
　なお、フリーローラ１６１によるフレキシブルプリント基板ＦＡの挟み込みの後に、ピン押し出し機構１４０を差込孔２１１ａとＹ方向で同軸となる位置まで移動させる。しかしながら、ピン押し出し機構１４０の移動は、フリーローラ１６１によるフレキシブルプリント基板ＦＡの挟み込みの前であっても良く、次の第４工程において行うようにしても良い。 In addition, after pinching the flexible printed circuit board FA by the free roller 161, the pin pushing mechanism 140 is moved to a position coaxial with the insertion hole 211a in the Y direction. However, the movement of the pin pushing mechanism 140 may be performed before the flexible printed circuit board FA is sandwiched by the free rollers 161, or may be performed in the next fourth step.
　（４）第４工程：差込孔２１１ａへの可動ピン２５ａの差し込み（掛け回し工程の一部に対応）
　続いて、図１６および図１７に示すように、ローラ駆動機構１７０の駆動モータ１７１を作動させて、駆動ローラ１５１ａをフレキシブルプリント基板ＦＡの送出方向とは逆方向（図１６における左方向）に駆動する。それにより、フレキシブルプリント基板ＦＡがたるむことが可能となり、フリーローラ１６１が下降可能な状態となる。ただし、駆動ローラ１５１ａをフレキシブルプリント基板ＦＡの送出方向に駆動するように、駆動モータ１７１を作動させても良いが、この場合には、駆動トルクを上述の第３工程等に示す場合よりも弱くすることが好ましい。 (4) Fourth step: Inserting the movable pin 25a into the insertion hole 211a (corresponding to a part of the winding step)
Subsequently, as shown in FIGS. 16 and 17, the drive motor 171 of the roller drive mechanism 170 is operated to drive the drive roller 151a in the direction opposite to the delivery direction of the flexible printed circuit board FA (the left direction in FIG. 16). To do. As a result, the flexible printed circuit board FA can sag, and the free roller 161 can be lowered. However, the drive motor 171 may be operated so as to drive the drive roller 151a in the delivery direction of the flexible printed circuit board FA. However, in this case, the drive torque is weaker than in the case of the third step described above. It is preferable to do.
　かかる駆動ローラ１５１ａの駆動状態において、フリーローラ接離機構１６０のエアシリンダ１６２を作動させて、フリーローラ１６１を下降させる。この下降は、差込孔２１１ａに可動ピン２５ａを差し込んだときに、可動ピン２５ａがフレキシブルプリント基板ＦＡよりも搬送ラインＬ側（上方側）に位置させるものであり、そのような位置となるようにフリーローラ１６１を下降させる。なお、このとき、治具スライダ１３０のスライドモータ１３１を作動させて、基板製造用治具１０を長手方向の他方側（Ｘ１側；図１６の右側）に移動させるようにしても良い。 In the driving state of the driving roller 151a, the air cylinder 162 of the free roller contact / separation mechanism 160 is operated to lower the free roller 161. This lowering is such that when the movable pin 25a is inserted into the insertion hole 211a, the movable pin 25a is positioned closer to the transport line L (upper side) than the flexible printed circuit board FA. The free roller 161 is lowered. At this time, the slide motor 131 of the jig slider 130 may be operated to move the board manufacturing jig 10 to the other side in the longitudinal direction (X1 side; right side in FIG. 16).
　その下降の後に、ピン押し出し機構１４０のエアシリンダ１４１を作動させて、鍔部２５２が本体部２１に当接するまで可動ピン２５ａを差込孔２１１ａに差し込む。それにより、可動ピン２５ａのピン部２５１が手前側（Ｙ１側）に突出し、そのピン部２５１にフレキシブルプリント基板ＦＡの上面側が接触可能な状態となる。なお、かかるエアシリンダ１４１の作動後には、エアシリンダ１４１が戻り、スリーブ３３へエアシリンダ１４１が入り込まないようにする。 After the lowering, the air cylinder 141 of the pin pushing mechanism 140 is operated, and the movable pin 25a is inserted into the insertion hole 211a until the flange portion 252 contacts the main body portion 21. Thereby, the pin part 251 of the movable pin 25a protrudes to the near side (Y1 side), and the upper surface side of the flexible printed circuit board FA can come into contact with the pin part 251. After the air cylinder 141 is actuated, the air cylinder 141 returns so that the air cylinder 141 does not enter the sleeve 33.
　（５）第５工程：差込孔２１１ｂへの可動ピン２５ｂの差し込み（掛け回し工程の一部に対応）
　次に、図１８および図１９に示すように、差込孔２１１ｂへの可動ピン２５ｂの差し込みを行う。そのために、ローラ駆動機構１７０の駆動モータ１７１を作動させて、駆動ローラ１５１ａを送出方向（図１８における右方向）に駆動させつつ、フリーローラ１６１が上昇する。その後に、治具スライダ１３０のスライドモータ１３１を作動させて、基板製造用治具１０を長手方向の一方側（Ｘ２側；図１８の左側）に移動させ、差込孔２１１ｂに可動ピン２５ｂを差し込んだときに、可動ピン２５ｂがフレキシブルプリント基板ＦＡよりも搬送ラインＬ側（下方側）に位置させるようにする。 (5) Fifth step: Inserting the movable pin 25b into the insertion hole 211b (corresponding to a part of the winding step)
Next, as shown in FIGS. 18 and 19, the movable pin 25b is inserted into the insertion hole 211b. Therefore, the free roller 161 is raised while operating the drive motor 171 of the roller drive mechanism 170 to drive the drive roller 151a in the delivery direction (right direction in FIG. 18). Thereafter, the slide motor 131 of the jig slider 130 is operated to move the board manufacturing jig 10 to one side in the longitudinal direction (X2 side; left side in FIG. 18), and the movable pin 25b is inserted into the insertion hole 211b. When inserted, the movable pin 25b is positioned closer to the transport line L (lower side) than the flexible printed circuit board FA.
　その後に、ピン押し出し機構１４０を差込孔２１１ｂとＹ方向で同軸となる位置まで移動させる。その移動後に、ピン押し出し機構１４０のエアシリンダ１４１を作動させて、鍔部２５２が本体部２１に当接するまで可動ピン２５ｂを差込孔２１１ｂに差し込む。それにより、可動ピン２５ｂのピン部２５１が手前側（Ｙ１側）に突出し、そのピン部２５１にフレキシブルプリント基板ＦＡの下面側が接触可能な状態となる。なお、かかるエアシリンダ１４１の作動後には、エアシリンダ１４１が戻り、スリーブ３３へエアシリンダ１４１が入り込まないようにする。 Thereafter, the pin push-out mechanism 140 is moved to a position coaxial with the insertion hole 211b in the Y direction. After the movement, the air cylinder 141 of the pin push-out mechanism 140 is operated, and the movable pin 25b is inserted into the insertion hole 211b until the flange portion 252 contacts the main body portion 21. Thereby, the pin part 251 of the movable pin 25b protrudes to the near side (Y1 side), and the lower surface side of the flexible printed circuit board FA can come into contact with the pin part 251. After the air cylinder 141 is actuated, the air cylinder 141 returns so that the air cylinder 141 does not enter the sleeve 33.
　（６）第６工程：第４工程と第５工程と同様の動作の繰り返し（掛け回し工程の一部に対応）
　上述の第５工程の後は、第４工程と第５工程と同様の動作を順次繰り返し、差込孔２１１ｃ～２１１ｉまで可動ピン２５ｃ～２５ｉを差し込みつつ、それぞれの可動ピン２５ｃ～２５ｉにフレキシブルプリント基板ＦＡが掛け回される状態とする。 (6) Sixth step: Repeating the same operation as the fourth and fifth steps (corresponding to a part of the wrapping step)
After the fifth step, the same operations as those in the fourth step and the fifth step are sequentially repeated, and the flexible pins 25c to 25i are inserted into the insertion holes 211c to 211i, and flexible printing is performed on the movable pins 25c to 25i. The state is such that the substrate FA is wound around.
　（７）第７工程：フリーローラ１６１の開放
　可動ピン２５ｉにフレキシブルプリント基板ＦＡが掛け回された状態とした後に、図２０および図２１に示すように、駆動モータ１７１を作動させて駆動ローラ１５１ａを送り方向に駆動させつつ、エアシリンダ１６２の作動を停止させて、付勢手段の付勢力によってフリーローラ１６１を開放する。 (7) Seventh step: opening of the free roller 161 After the flexible printed circuit board FA is wound around the movable pin 25i, as shown in FIGS. 20 and 21, the drive motor 171 is operated to drive the drive roller 151a. Is driven in the feed direction, the operation of the air cylinder 162 is stopped, and the free roller 161 is opened by the urging force of the urging means.
　（８）第８工程：トルクローラ１５１の開放
　続いて、図２２および図２３に示すように、後端保持部材２００と終端固定部材２６とでフレキシブルプリント基板ＦＡを挟み込む（第２保持工程に対応）。その後に、エアシリンダ１５２の作動を停止させて、付勢手段の付勢力によってトルクローラ１５１を開放する。このようにして、フレキシブルプリント基板ＦＡの基板製造用治具１０への取り付けが終了する。 (8) Eighth Step: Release of Torque Roller 151 Subsequently, as shown in FIGS. 22 and 23, the flexible printed circuit board FA is sandwiched between the rear end holding member 200 and the terminal end fixing member 26 (corresponding to the second holding step). ). Thereafter, the operation of the air cylinder 152 is stopped, and the torque roller 151 is opened by the urging force of the urging means. Thus, the attachment of the flexible printed circuit board FA to the board manufacturing jig 10 is completed.
　（９）第９工程：フレキシブルプリント基板ＦＡの加熱成形
　次に、図２４および図２５に示すように、フレキシブルプリント基板ＦＡが取り付けられた第１治具２０を第２治具３０から取り外す。そして、フレキシブルプリント基板ＦＡにテンションが掛かった状態で、第１治具２０と共にフレキシブルプリント基板ＦＡをオーブン等で加熱する（加熱成形工程に対応）。それにより、フレキシブルプリント基板ＦＢが成形される。かかる加熱温度としては、２００℃程度で３０分程度加熱するものがある。このように、フレキシブルプリント基板ＦＡの先端側の位置が定まった状態で、かつフレキシブルプリント基板ＦＡにテンションが掛かった状態で加熱成形されるため、成形後のフレキシブルプリント基板ＦＢの製品形状を安定させることができる。 (9) Ninth Step: Thermoforming of Flexible Printed Circuit Board FA Next, as shown in FIGS. 24 and 25, the first jig 20 to which the flexible printed circuit board FA is attached is removed from the second jig 30. Then, the flexible printed circuit board FA is heated together with the first jig 20 in an oven or the like in a state where tension is applied to the flexible printed circuit board FA (corresponding to a thermoforming process). Thereby, the flexible printed circuit board FB is molded. As such a heating temperature, there is one which is heated at about 200 ° C. for about 30 minutes. As described above, since the heat-molding is performed in a state where the position of the front end side of the flexible printed circuit board FA is determined and the tension is applied to the flexible printed circuit board FA, the product shape of the formed flexible printed circuit board FB is stabilized. be able to.
　なお、加熱成形によって成形後のフレキシブルプリント基板ＦＢを得た後には、フレキシブルプリント基板ＦＢを第１治具２０から取り外す。この場合、図２６に示すように、第１治具２０のうち奥側（Ｙ２側）に凹部２７を設け、この凹部２７に抜き板２８が嵌め込まれる構成としても良い。かかる抜き板２８には、差込孔２１１と同軸かつ同等の孔径の孔部２８ａが設けられている。それにより、それぞれの可動ピン２５の鍔部２５２は抜き板２８を通過できず、当該抜き板２８の側面に係止される状態となる。そのため、抜き板２８を凹部２７から外すことで、可動ピン２５を差込孔２１１から引き抜くことができ、フレキシブルプリント基板ＦＢを第１治具２０から容易に取り外すことができる。 In addition, after obtaining the molded flexible printed circuit board FB by thermoforming, the flexible printed circuit board FB is removed from the first jig 20. In this case, as shown in FIG. 26, a recess 27 may be provided on the back side (Y2 side) of the first jig 20, and the extraction plate 28 may be fitted into the recess 27. The punching plate 28 is provided with a hole portion 28a that is coaxial with the insertion hole 211 and has the same diameter. Thereby, the flange 252 of each movable pin 25 cannot pass through the punching plate 28 and is locked to the side surface of the punching plate 28. Therefore, by removing the extraction plate 28 from the recess 27, the movable pin 25 can be pulled out from the insertion hole 211, and the flexible printed circuit board FB can be easily detached from the first jig 20.
　また、図２７に示すように、第１治具２０が分割可能な構成としても良い。たとえば、第１治具２０は、その上下方向（Ｚ方向）の中途にある分割部位２９から、手前側（Ｙ１側）の側面またはその近傍を支点として、第１分割部位２０Ａと第２分割部位２０Ｂの２つの部位に分かれるように開閉する構成としても良い。ここで、分割部位２９は、下方側（Ｚ２側）に位置する可動ピン２５とも上方側（Ｚ１側）に位置する可動ピン２５の間の位置に設ける構成とするのが好ましい。 Further, as shown in FIG. 27, the first jig 20 may be divided. For example, the first jig 20 has a first divided part 20A and a second divided part from the divided part 29 in the middle of the vertical direction (Z direction) as a fulcrum on the side surface on the near side (Y1 side) or the vicinity thereof. It is good also as a structure opened and closed so that it may be divided into two parts of 20B. Here, it is preferable that the divided portion 29 is provided at a position between the movable pin 25 located on the lower side (Z2 side) and the movable pin 25 located on the upper side (Z1 side).
　かかる図２７に示す構成とする場合、分割部位２９を支点として第１治具２０を開くようにすると、第１治具２０とフレキシブルプリント基板ＦＢとの間のテンションが緩み、フレキシブルプリント基板ＦＢを第１治具２０から容易に取り外すことができる。 27, when the first jig 20 is opened with the divided portion 29 as a fulcrum, the tension between the first jig 20 and the flexible printed circuit board FB is loosened, and the flexible printed circuit board FB is removed. It can be easily removed from the first jig 20.
　（１０）第１０工程：切り落とし部Ｆ４のカット
　続いて、図２８および図２９に示すように、プリーツ状に成形されたフレキシブルプリント基板ＦＢを出荷できる状態とするために、成形されたフレキシブルプリント基板ＦＢの不要部分である切り落とし部Ｆ４のカットを行う。それにより、最終製品が完成する。かかる立体的に成形されたフレキシブルプリント基板ＦＢの成形形状を保持したままカットするために、図２８および図２９に示すような刃付治具３００と固定治具４００を用いる。 (10) Tenth step: Cut of the cut-off portion F4 Subsequently, as shown in FIGS. 28 and 29, the flexible printed circuit board formed in order to be able to ship the flexible printed circuit board FB formed in a pleat shape. The cut-off portion F4 that is an unnecessary part of the FB is cut. Thereby, the final product is completed. In order to cut the three-dimensionally shaped flexible printed circuit board FB while maintaining the molded shape, a jig 300 with a blade and a fixing jig 400 as shown in FIGS. 28 and 29 are used.
　刃付治具３００は、ピナクルや金型等のような刃付の治具であり、フレキシブルプリント基板ＦＢの両端側の切り落とし部Ｆ４をカット可能なように刃部３０１が一対設けられている。また、固定治具４００は、窪んだ形状の治具筐体４０１を備えている。その治具筐体４０１の窪みの周囲には、孔部Ｆ５を差し込み可能なガイドピン４０２が設けられており、フレキシブルプリント基板ＦＢの先端側を保持可能としている。さらに、固定治具４００は、フレキシブルプリント基板ＦＢの後端側を位置決めしつつ保持可能な後端保持部４０３を備えている。そのため、刃付治具３００を下方に移動させることで、フレキシブルプリント基板ＦＢの両端側の切り落とし部Ｆ４をカットすることが可能となっている。 The jig with blade 300 is a jig with a blade such as a pinnacle or a mold, and a pair of blade portions 301 are provided so that the cut-off portions F4 on both ends of the flexible printed circuit board FB can be cut. The fixing jig 400 includes a jig housing 401 having a recessed shape. A guide pin 402 into which the hole F5 can be inserted is provided around the recess of the jig housing 401 so that the front end side of the flexible printed circuit board FB can be held. Furthermore, the fixing jig 400 includes a rear end holding portion 403 that can be held while positioning the rear end side of the flexible printed circuit board FB. Therefore, by moving the jig with blade 300 downward, it is possible to cut off the cut-off portions F4 on both ends of the flexible printed circuit board FB.
　なお、図２９に示す構成では、固定治具４００は、複数のフレキシブルプリント基板ＦＢを取り付け可能としており、刃付治具３００を用いて複数のフレキシブルプリント基板ＦＢを一度に切断することが可能である。ただし、フレキシブルプリント基板ＦＢを一つずつ切断するようにしても良い。 In the configuration shown in FIG. 29, the fixing jig 400 can attach a plurality of flexible printed boards FB, and the plurality of flexible printed boards FB can be cut at once using the bladed jig 300. is there. However, the flexible printed circuit boards FB may be cut one by one.
　以上のような刃付治具３００および固定治具４００を用いて、両端側の切り落とし部Ｆ４のカットを行うことにより、最終製品が完成する。 Using the above-mentioned jig 300 with a blade and the fixing jig 400, the cut-off portion F4 on both ends is cut to complete the final product.
　なお、フレキシブルプリント基板ＦＢの後端側には、孔部Ｆ５と同様の孔部を予め設けておき、その後端側においても、ガイドピン４０１と同様のガイドピンに孔部を差し込むことで、位置決めを行うようにしても良い。また、切り落とし部Ｆ４のカットは、上述した手法以外の手法を用いても良い。そのような手法としては、たとえばレーザを用いたレーザカットや、ルータビットを用いたルータカット等が挙げられる。 In addition, a hole similar to the hole F5 is provided in advance on the rear end side of the flexible printed circuit board FB, and positioning is also performed by inserting the hole into a guide pin similar to the guide pin 401 on the rear end side. May be performed. In addition, a method other than the method described above may be used for cutting the cut-off portion F4. Examples of such methods include laser cutting using a laser and router cutting using a router bit.
［比較例について］
　続いて、本実施の形態に対する比較例について説明する。図３０は、比較例に係る基板製造用治具１０Ｄの構成を示す側面図であり、上述した特許文献３に関するものである。図３０に示すように、比較例に係る基板製造用治具１０Ｄは、本体部１１を備え、その本体部１１には、複数の固定ピン２４Ｄが設けられている。 [Comparative example]
Then, the comparative example with respect to this Embodiment is demonstrated. FIG. 30 is a side view illustrating a configuration of a substrate manufacturing jig 10D according to a comparative example, and relates to the above-described Patent Document 3. As illustrated in FIG. 30, the substrate manufacturing jig 10 </ b> D according to the comparative example includes a main body portion 11, and the main body portion 11 is provided with a plurality of fixing pins 24 </ b> D.
　この場合、一定テンションを加えながら、フレキシブルプリント基板ＦＡを固定ピン２４Ｄの間に通していく。そして、フレキシブルプリント基板ＦＡを固定ピン２４Ｄの間に通した後に、加熱成形を行っている。この場合、固定ピン２４Ｄの間にフレキシブルプリント基板ＦＡを通す作業性は悪く、しかもフレキシブルプリント基板ＦＡの始点側の位置（先端側の位置）が安定しない。また、フレキシブルプリント基板ＦＡと固定ピン２４Ｄとの間での摩擦により、一定テンションでの引っ張りは困難である。したがって、成形形状の安定化が難しい。特に、固定ピン２４Ｄの本数が多くなると摩擦が大きくなり、一定テンションで引っ張ることが困難となる。また、摩擦の増大に伴い、一定のテンションを加えても、フレキシブルプリント基板ＦＡの途中が緩んでしまう、という問題もある。 In this case, the flexible printed circuit board FA is passed between the fixing pins 24D while applying a certain tension. Then, after the flexible printed circuit board FA is passed between the fixing pins 24D, heat molding is performed. In this case, the workability of passing the flexible printed circuit board FA between the fixing pins 24D is poor, and the position on the starting point side (the position on the front end side) of the flexible printed circuit board FA is not stable. In addition, it is difficult to pull at a constant tension due to friction between the flexible printed circuit board FA and the fixing pin 24D. Therefore, it is difficult to stabilize the molded shape. In particular, when the number of fixing pins 24D increases, the friction increases and it is difficult to pull the pin with a constant tension. In addition, as the friction increases, there is a problem that the middle of the flexible printed circuit board FA is loosened even if a certain tension is applied.
　図３１は、フレキシブルプリント基板ＦＢの成形形状が安定しない例を示す側面図である。図３１（Ａ）は、狙いとするフレキシブルプリント基板ＦＢの形状を示している。しかし、図３１（Ｂ）では、その狙いとするフレキシブルプリント基板ＦＢに対し、曲成部ＦＢ１の曲率（Ｒ）がばらついている状態を示している。すなわち、曲成部ＦＢ１の曲率（Ｒ）が大きい部分ＦＢ１ａと小さい部分ＦＢ１ｂとが形成されており、成形形状が安定しない一態様となっている。 FIG. 31 is a side view showing an example in which the molding shape of the flexible printed circuit board FB is not stable. FIG. 31A shows the shape of the target flexible printed circuit board FB. However, FIG. 31B shows a state in which the curvature (R) of the bent portion FB1 varies with respect to the target flexible printed circuit board FB. That is, a portion FB1a having a large curvature (R) and a portion FB1b having a small curvature (R) of the bent portion FB1 are formed, which is an aspect in which the molded shape is not stable.
　また、図３１（Ｃ）では、基板製造用治具１０Ｄにセットしたフレキシブルプリント基板ＦＡの始点側（先端側）の位置がＭだけずれた例を示している。このような始点側（先端側）の位置ずれも、成形形状が安定しない一態様となっている。 Further, FIG. 31C shows an example in which the position of the starting point side (tip side) of the flexible printed circuit board FA set on the substrate manufacturing jig 10D is shifted by M. Such misalignment of the starting point side (tip side) is also an aspect in which the molding shape is not stable.
＜効果について＞
　以上のようなフレキシブルプリント基板ＦＢの製造方法、基板製造用治具１０および基板製造装置１００によると、次のような効果が生じる。 <About effects>
According to the manufacturing method of the flexible printed circuit board FB, the substrate manufacturing jig 10 and the substrate manufacturing apparatus 100 as described above, the following effects are produced.
　すなわち、先端固定部材２３（掛止ピン２３ｂ）により、フレキシブルプリント基板ＦＡの一端側（Ｘ２側；始点側）の位置を定めることができるので、フレキシブルプリント基板ＦＢの始点側で位置ずれが生じるのを防止可能となる。それにより、フレキシブルプリント基板ＦＢの成形形状を安定化させることができる。 That is, since the position of one end side (X2 side; starting point side) of the flexible printed circuit board FA can be determined by the tip fixing member 23 (the latching pin 23b), a positional deviation occurs on the starting point side of the flexible printed circuit board FB. Can be prevented. Thereby, the shaping | molding shape of the flexible printed circuit board FB can be stabilized.
　また、固定ピン２４および可動ピン２５にフレキシブルプリント基板ＦＡを掛け回す状態で支持させることができるので、フレキシブルプリント基板ＦＡに曲成部ＦＢ１を確実に形成することができる。さらに、終端固定部材２６では、フレキシブルプリント基板ＦＡの他端側（Ｘ１側；終端側）を支持させることができる。それにより、フレキシブルプリント基板ＦＡを加熱成形する際でも、フレキシブルプリント基板ＦＡにテンションを与えた状態を維持することができる。 Further, since the flexible printed circuit board FA can be supported around the fixed pin 24 and the movable pin 25, the bent portion FB1 can be reliably formed on the flexible printed circuit board FA. Further, the end fixing member 26 can support the other end side (X1 side; end side) of the flexible printed circuit board FA. Thereby, even when the flexible printed circuit board FA is heat-molded, it is possible to maintain a state in which the flexible printed circuit board FA is tensioned.
　また、本実施の形態では、基板製造用治具１０は、第１治具２０と第２治具３０とを有し、第２治具３０に対して第１治具２０が着脱可能に設けられている。そのため、フレキシブルプリント基板ＦＡを加熱成形する際には、第２治具３０から第１治具２０を取り外すことができるので、基板製造用治具１０の全体を加熱せずに済み、オーブン等での加熱成形に際して熱容量を小さくすることができる。 In the present embodiment, the substrate manufacturing jig 10 includes a first jig 20 and a second jig 30, and the first jig 20 is detachably provided to the second jig 30. It has been. Therefore, when the flexible printed circuit board FA is thermoformed, the first jig 20 can be removed from the second jig 30, so that it is not necessary to heat the entire board manufacturing jig 10, such as in an oven. The heat capacity can be reduced during the thermoforming.
　しかも、第１治具２０には、先端固定部材２３と、固定ピン２４および可動ピン２５と、終端固定部材２６とが設けられていて、フレキシブルプリント基板ＦＡの一端側（Ｘ２側）を先端固定部材２３側で支持させつつ、フレキシブルプリント基板ＦＡの他端側（Ｘ１側）を終端固定部材２６側で支持させることができる。それにより、フレキシブルプリント基板ＦＡを固定ピン２４および可動ピン２５で湾曲させつつ良好な加熱成形を行わせることができる。 Moreover, the first jig 20 is provided with a tip fixing member 23, a fixed pin 24, a movable pin 25, and a terminal fixing member 26, and one end side (X2 side) of the flexible printed circuit board FA is fixed to the tip. The other end side (X1 side) of the flexible printed circuit board FA can be supported on the terminal fixing member 26 side while being supported on the member 23 side. Thereby, it is possible to perform favorable heat forming while bending the flexible printed circuit board FA with the fixed pins 24 and the movable pins 25.
　また、可動ピン２５は、第１治具２０に対して着脱自在に設けられている。そのため、可動ピン２５にフレキシブルプリント基板ＦＡを掛け回す際には、必要とする可動ピン２５を差込孔２１１に差し込むようにすることで、可動ピン２５の間にフレキシブルプリント基板ＦＡを通す等のような手間のかかる作業を行わずに済む。そのため、フレキシブルプリント基板ＦＡを基板製造用治具１０にセットする作業が容易に行える。 The movable pin 25 is detachably attached to the first jig 20. For this reason, when the flexible printed circuit board FA is hung around the movable pin 25, the flexible printed circuit board FA is passed between the movable pins 25 by inserting the necessary movable pins 25 into the insertion holes 211. This eliminates the time-consuming work. Therefore, the work of setting the flexible printed circuit board FA to the board manufacturing jig 10 can be easily performed.
　なお、第２治具３０には、可動ピン２５を入り込ませると共に差込孔２１１と同軸となる位置にスリーブ３３が設けられている。そのため、差込孔２１１への可動ピン２５の差し込みを容易に行える。また、フレキシブルプリント基板ＦＡを第１治具２０にセットする前の状態ではスリーブ３３に可動ピン２５を入り込ませておくことで、可動ピン２５の差込孔２１１への差し込みを効率良く行わせることができる。 The second jig 30 is provided with a sleeve 33 at a position where the movable pin 25 is inserted and is coaxial with the insertion hole 211. Therefore, the movable pin 25 can be easily inserted into the insertion hole 211. In addition, before the flexible printed circuit board FA is set on the first jig 20, the movable pin 25 is inserted into the insertion hole 211 efficiently by inserting the movable pin 25 into the sleeve 33. Can do.
　さらに、本実施の形態では、先端固定部材２３には、先端受部２３ａと掛止ピン２３ｂとが設けられている。そのため、フレキシブルプリント基板ＦＡの一端側（Ｘ２側；始点側）の位置を容易かつ確実に定めることが可能となる。それにより、フレキシブルプリント基板ＦＡの始点側で位置ずれが生じるのを一層確実に防止可能となり、フレキシブルプリント基板ＦＡの成形形状を一層安定化させることができる。 Furthermore, in the present embodiment, the tip fixing member 23 is provided with a tip receiving portion 23a and a latch pin 23b. Therefore, the position of one end side (X2 side; starting point side) of the flexible printed circuit board FA can be easily and reliably determined. Thereby, it is possible to more reliably prevent the displacement from occurring at the starting point side of the flexible printed circuit board FA, and the molded shape of the flexible printed circuit board FA can be further stabilized.
　また、本実施の形態では、基板製造装置１００には、先端挟持部材１８１とエアシリンダ１８２とを有する先端保持機構１８０が設けられている。このため、先端固定部材２３に対してエアシリンダ１８２で先端挟持部材１８１を駆動することにより、フレキシブルプリント基板ＦＡの一端側（Ｘ２側）を確実に挟持させることができる。それにより、一端側（Ｘ２側；始点側）の位置を一層確実に定めることが可能となる。したがって、フレキシブルプリント基板ＦＡの始点側で位置ずれが生じるのを一層確実に防止可能となり、フレキシブルプリント基板ＦＡの成形形状を一層安定化させることができる。 In the present embodiment, the substrate manufacturing apparatus 100 is provided with a tip holding mechanism 180 having a tip clamping member 181 and an air cylinder 182. For this reason, by driving the tip clamping member 181 with the air cylinder 182 with respect to the tip fixing member 23, one end side (X2 side) of the flexible printed circuit board FA can be securely clamped. Thereby, the position of one end side (X2 side; starting point side) can be determined more reliably. Accordingly, it is possible to more reliably prevent the displacement from occurring on the starting point side of the flexible printed circuit board FA, and the molded shape of the flexible printed circuit board FA can be further stabilized.
　また、本実施の形態では、基板製造用治具１０には、治具スライダ１３０のスライドモータ１３１によってスライドのための駆動力が与えられる。そのため、フレキシブルプリント基板ＦＡを固定ピン２４または可動ピン２５に掛け回す際には、所望する位置に基板製造用治具１０を移動させることが可能となり、フレキシブルプリント基板ＦＡの基板製造用治具１０（第１治具２０）へのセットを容易に実施可能となる。 In the present embodiment, the substrate manufacturing jig 10 is given a driving force for sliding by the slide motor 131 of the jig slider 130. Therefore, when the flexible printed board FA is hung around the fixed pin 24 or the movable pin 25, the board manufacturing jig 10 can be moved to a desired position. Setting to the (first jig 20) can be easily performed.
　さらに、本実施の形態では、基板製造装置１００には、トルクローラ接離機構１５０、フリーローラ接離機構１６０およびローラ駆動機構１７０が設けられている。そのため、フレキシブルプリント基板ＦＡにローラ駆動機構１７０によってトルクローラ１５１を駆動させてテンションを与えつつ、エアシリンダ１６２でフリーローラ１６１を上昇または下降させることができる。それにより、フレキシブルプリント基板ＦＡを固定ピン２４または可動ピン２５に掛け回す作業を自動的に実施することが可能となる。この際に、治具スライダ１３０によって基板製造用治具１０を移動させることにより、可動ピン２５を曲成部ＦＢ１に対応する位置に容易に差し込ませることが可能となる。 Furthermore, in the present embodiment, the substrate manufacturing apparatus 100 is provided with a torque roller contact / separation mechanism 150, a free roller contact / separation mechanism 160, and a roller drive mechanism 170. Therefore, the free roller 161 can be raised or lowered by the air cylinder 162 while the torque is applied to the flexible printed circuit board FA by the roller driving mechanism 170 to give the tension. Accordingly, it is possible to automatically perform the operation of hanging the flexible printed circuit board FA around the fixed pin 24 or the movable pin 25. At this time, by moving the substrate manufacturing jig 10 by the jig slider 130, the movable pin 25 can be easily inserted into a position corresponding to the bent portion FB1.
　また、本実施の形態では、基板製造装置１００には、側面押当部材１９１を有する側面押当機構１９０が設けられている。そして、エアシリンダ１９２を作動させてフレキシブルプリント基板ＦＡの側面に側面押当部材１９１を押し当てることで、フレキシブルプリント基板ＦＡのスキュー方向の調整を容易かつ確実に実施することが可能となる。 In the present embodiment, the substrate manufacturing apparatus 100 is provided with a side surface pressing mechanism 190 having a side surface pressing member 191. Then, by operating the air cylinder 192 and pressing the side pressing member 191 against the side surface of the flexible printed circuit board FA, the skew direction of the flexible printed circuit board FA can be adjusted easily and reliably.
＜変形例＞
　以上、本発明の一実施の形態について説明したが、本発明はこれ以外にも種々変形可能となっている。以下、それについて述べる。 <Modification>
Although one embodiment of the present invention has been described above, the present invention can be variously modified in addition to this. This will be described below.
　上述の実施の形態においては、ある特定の直径の固定ピン２４および可動ピン２５を用いてフレキシブルプリント基板ＦＡの加熱成形を行う場合について説明している。しかしながら、フレキシブルプリント基板ＦＡの加熱成形は、異なる直径の固定ピン２４および可動ピン２５を組み合わせて行うようにしても良い。また、フレキシブルプリント基板ＦＡの湾曲部分のピッチ（曲成部ＦＢ１となる部分のピッチ）を変更するようにしても良い。図３２は、かかる様子を示す図である。 In the above-described embodiment, the case where the flexible printed circuit board FA is formed by heating using the fixed pin 24 and the movable pin 25 having a specific diameter has been described. However, the heat forming of the flexible printed circuit board FA may be performed by combining the fixed pin 24 and the movable pin 25 having different diameters. Moreover, you may make it change the pitch (pitch of the part used as the bending part FB1) of the curved part of flexible printed circuit board FA. FIG. 32 is a diagram showing such a state.
　図３２では、小径の固定ピン２４および可動ピン２５を用いる部分と、大径の固定ピン２４と可動ピン２５を用いる構成とが組み合わされている。また、図３２では、小径の固定ピン２４および可動ピン２５が用いられる部分では、フレキシブルプリント基板ＦＡの湾曲部分のピッチ（曲成部ＦＢ１となる部分のピッチ）が狭く、大径の固定ピン２４および可動ピン２５が用いられる部分では、フレキシブルプリント基板ＦＡの湾曲部分のピッチ（曲成部ＦＢ１となる部分のピッチ）が広い。 32, the portion using the small-diameter fixed pin 24 and the movable pin 25 and the configuration using the large-diameter fixed pin 24 and the movable pin 25 are combined. In FIG. 32, in the portion where the small-diameter fixed pin 24 and the movable pin 25 are used, the pitch of the curved portion of the flexible printed circuit board FA (the pitch of the portion that becomes the bent portion FB1) is narrow, and the large-diameter fixed pin 24 is. In the portion where the movable pin 25 is used, the pitch of the curved portion of the flexible printed circuit board FA (the pitch of the portion that becomes the bent portion FB1) is wide.
　このように構成することで、曲成部ＦＢ１の曲率や曲成部ＦＢ１の間の部分のピッチを自由に組み合わせてフレキシブルプリント基板ＦＢを製作することが可能となる。たとえば、フレキシブルプリント基板ＦＢのうち小径でピッチが狭い成形部分は、配置スペースの狭い個所で伸縮が必要な個所に好適である。また、大径でピッチが広い成形部分は、設置スペースが広く、伸縮量が大きい個所に好適である。 With this configuration, it is possible to manufacture the flexible printed circuit board FB by freely combining the curvature of the bent portion FB1 and the pitch of the portion between the bent portions FB1. For example, a molded part having a small diameter and a narrow pitch in the flexible printed circuit board FB is suitable for a place where expansion and contraction is required in a place where the arrangement space is narrow. In addition, a molded part having a large diameter and a wide pitch is suitable for a place having a large installation space and a large amount of expansion and contraction.
　また、図３２に示す構成では、ピッチが狭い部分とピッチが広い部分との間に、成形がされない領域も存在しており、かかる成形されない領域の存在によって加熱成形する部位を最小限とすることも可能となり、成形前のフレキシブルプリント基板ＦＡの長さを短くすることも可能となる。それにより、製品コストを低減することも可能となる。 Further, in the configuration shown in FIG. 32, there is a region where molding is not performed between a portion where the pitch is narrow and a portion where the pitch is wide, and the portion to be heat-molded is minimized due to the presence of the region where the pitch is not formed. The length of the flexible printed circuit board FA before molding can be shortened. Thereby, the product cost can be reduced.
　このように、種々のピッチを有するフレキシブルプリント基板ＦＢを、加熱成形する部位がない領域も含めて一体的に扱えるため、異なるピッチのフレキシブルプリント基板ＦＢ同士を接続する接続部等も不要となる。 As described above, since the flexible printed circuit board FB having various pitches can be handled integrally including a region where there is no part to be thermoformed, a connecting portion for connecting the flexible printed circuit boards FB having different pitches becomes unnecessary.
　また、上述の実施の形態においては、基板製造用治具１０に１つのフレキシブルプリント基板ＦＡをセットする場合について説明している。しかしながら、複数のフレキシブルプリント基板ＦＡを１つの基板製造用治具１０に取り付ける構成を採用しても良い。図３３は、このような基板製造用治具１０Ｂを示す。 In the above-described embodiment, the case where one flexible printed circuit board FA is set in the board manufacturing jig 10 has been described. However, a configuration in which a plurality of flexible printed boards FA are attached to one board manufacturing jig 10 may be adopted. FIG. 33 shows such a substrate manufacturing jig 10B.
　図３３では、複数（図３３では３つ）のフレキシブルプリント基板ＦＡの一端側および他端側に位置する切り落とし部が互いに連結されて、長さの長い１つの切り落とし部Ｆ４Ｂとなっている。このような一体的な切り落とし部Ｆ４Ｂを設ける場合には、位置決め等がより正確に行える。ただし、フレキシブルプリント基板ＦＡ同士が連結されずに、互いに独立した構成としても良い。 In FIG. 33, the cutout portions located on one end side and the other end side of a plurality (three in FIG. 33) of flexible printed circuit boards FA are connected to each other to form one long cutout portion F4B. When such an integrated cut-off portion F4B is provided, positioning or the like can be performed more accurately. However, the flexible printed circuit boards FA may be independent from each other without being connected to each other.
　また、一端側（Ｘ２側）の切り落とし部Ｆ４Ｂには、複数（図３３では３つ）の孔部Ｆ５が設けられている。そして、先端固定部材２３には、複数（図３３では３つ）の掛止ピン２３ｂが設けられている。この場合、固定ピン２４および可動ピン２５の長さを長くする必要があり、またエアシリンダ１４１のストロークや、トルクローラ１５１およびフリーローラ１６１のローラの幅も長くする必要がある。 Moreover, a plurality of (three in FIG. 33) hole portions F5 are provided in the cut-off portion F4B on one end side (X2 side). The tip fixing member 23 is provided with a plurality of (three in FIG. 33) latching pins 23b. In this case, it is necessary to increase the lengths of the fixed pin 24 and the movable pin 25, and it is also necessary to increase the strokes of the air cylinder 141 and the widths of the torque roller 151 and the free roller 161.
　このように構成する場合には、一度に複数のフレキシブルプリント基板ＦＡの加熱成形を行うことが可能となり、生産効率を向上させることが可能となる。 In the case of such a configuration, it becomes possible to perform heat molding of a plurality of flexible printed circuit boards FA at a time, and it is possible to improve production efficiency.
　なお、基板製造用治具１０は、たとえば第１治具２０のみから構成されるものとしても良い。また、第１治具２０においては、先端固定部材２３が存在すると共に支持部材として、複数の固定ピン２４のみが存在しても良く、またそれとは逆に複数の固定ピン２４のみが存在しても良い。 In addition, the jig | tool 10 for board | substrate manufacture is good also as what is comprised only from the 1st jig | tool 20, for example.
